What type of drawing provides the precise dimensions of a section of a larger plan?

The type of drawing that provides the precise dimensions of a section of a larger plan is a detail drawing. Detail drawings are essential in construction and fabrication, as they illustrate specific features, components, or assemblies of a structure with exact measurements and notes. These drawings focus on a single part or section of a project, ensuring that builders and fabricators understand exactly how to construct that part according to the design specifications. The clarity and specificity of detail drawings reduce ambiguity and errors during the construction process.

Blueprints, while providing a general overview of a project or its layout, do not typically offer the same level of detail needed for specific sections. Elevation drawings depict the vertical aspects of a structure but also lack the intricate details required for precise construction. Isometric drawings represent three-dimensional structures in two dimensions but are more about visual representation than providing specific dimensions. Thus, detail drawings are crucial for ensuring accuracy and precision in the building process.
